ULTIMODE M-203G is reliable media converter enabling the transmission of Ethernet data signal in two single-mode optical fibers at long distances - up to 20 km. The media converter has two SC connectors used to transmit (Tx) or receive (Rx) the signal. Optical signal is transmitted and received in the second transmission window of 1310 nm.

ULTIMODE devices have MDI/MDIX auto detection feature and automatically find and set the fastest connection speed and mode. "Store and forward" mechanism allows to verify the received data using checksum function.

Sensitivity of the receiver and output power of the transmitter are designed for transmissions up to 20 km. When the devices are used at distances below 2 km, a suitable optical attenuator should be employed (to avoid possible damage to the receiver).

NOTICE!! It is not allowed to look directly at the fiber port when the device is plugged. The radiation invisible for the human eye can damage the retina!

Why to choose fiber optics:

possibility of sending signal over long distances (low attenuation of optical fibers - e.g. for the wavelength of 1550 nm the attenuation is about 0.2 dB per kilometer, which means that the signal can be sent at a distance of 200 km - without regeneration)

ULTIMODE media converters are widely used for the transmission of Ethernet signals over long distances and in areas exposed to harsh weather conditions. Optical fibers provide full electrical insulation and resistance to electromagnetic interference. Media converters ULTIMODE M-203G are primarily used to connect building LANs (e.g. of scattered buildings of one corporation). Below there is a sample application of ULTIMODE converters.
